Return Value

Remarks

The edge objects are returned in a CW or CCW manner based on the direction of the ILoop2.

The loop direction is determined as follows: if a loop is viewed along its direction, with the face normal pointing upwards, then the face that owns the loop is to the left. This means that inner loops are CW and outer loops are CCW. To determine if a loop is an outer loop, see ILoop2::IsOuter.

Because an edge is shared by multiple loops, the edge direction may be opposite to the direction of the ILoop2. To check this, use IEdge::EdgeInFaceSense.
